Docker installation for the first time in life

Ubuntu Series installs Docker through the system comes with package installation

The Ubuntu 14.04 version of the system has its own Docker package, which can be installed directly.

$ sudo apt-get update$ sudo apt-get install -y docker.io$ sudo ln -sf /usr/bin/docker.io /usr/local/bin/docker$ sudo sed -i ‘$acomplete -F _docker docker‘ /etc/bash_completion.d/docker.io

If you install Docker using the operating system's own package, the currently installed version is the older 0.9.1. To install the updated version, you can do this by using the Docker source.

Install the latest version from the Docker source

To install the latest Docker version, you first need to install APT-TRANSPORT-HTTPS support and then install it by adding a source.

$ sudo apt-get install apt-transport-https$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9$ sudo bash -c "echo deb https://get.docker.io/ubuntu docker main > /etc/apt/sources.list.d/docker.list"$ sudo apt-get update$ sudo apt-get install lxc-docker

14.04 Previous Versions

If you have an older Ubuntu system, you need to update the kernel first.

$ sudo apt-get update$ sudo apt-get install linux-image-generic-lts-raring linux-headers-generic-lts-raring$ sudo reboot

Then repeat the above steps.

Start the Docker service after installation.

$ sudo service docker start
